Description

Technical Field

[0001] The invention relates to electric kettle technology, and in particular provides an electric kettle dumping and leakage prevention automatic control structure. Background Art

[0002] An electric kettle is a common household appliance used to heat water to a boiling or desired temperature. It typically consists of a heating element at the base of the kettle, a control unit, and a spout.

[0003] In some existing electric kettles, when the electric kettle is accidentally tipped over during use, the water in the kettle can easily leak out through the water outlet on the kettle body or the kettle lid can separate from the kettle body, causing safety hazards. In response to the above problems, some manufacturers have made improvements and upgrades to the water outlet, kettle lid and kettle body to solve the above problems. However, during use, due to the heating requirements of the kettle, an exhaust port needs to be provided. As a result, although safety structures are provided on the water outlet, kettle lid and kettle body, water can still leak out through the exhaust port after the kettle is tipped over, causing safety accidents.

[0004] There is currently no solution to the above problems on the market. Therefore, there is an urgent need to develop a kettle automatic control structure that can quickly close the exhaust port after the kettle is tipped over to avoid safety hazards caused by splashing high-temperature water. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an electric kettle tipping-proof and leak-proof automatic control structure, which solves the technical problem of potential safety hazards caused by high-temperature water leaking from the exhaust port when the kettle tips over.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions, namely:

[0007] The invention discloses an electric kettle dumping anti-leakage automatic control structure, comprising a leakage-proof valve assembly arranged in a cover body and a regulating component arranged in a handle, the cover body comprising a limiting groove formed on a seat plate, a discharge port being provided at the bottom of the limiting groove, and a leakage-proof valve assembly being installed in the limiting groove, the leakage-proof valve assembly comprising a driven slider, a spring and a sealing valve installed on the driven slider, one end of the driven slider abutting against the spring; the regulating component comprising a counterweight cavity formed by a plate body arranged in the handle, the inner edge surface of the counterweight cavity being in a conical shape with a larger upper portion and a smaller lower portion, and a rotating shaft being installed in the counterweight cavity, the rotating shaft being equipped with a rotating lever via a torsion spring, one end of the rotating lever being wedge-matched with the driven slider, and the other end of the rotating lever extending toward the inner side of the counterweight cavity to form a conical cavity, and a counterweight being arranged in the conical cavity.

For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0034] See Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of an electric kettle (or "electric water pot" or "electric thermos") is presented. Figure 2 Presented Figure 1 The cross-sectional view of the electric kettle is intended to fully demonstrate the design highlights of the electric kettle's tipping-proof and leak-proof automatic control structure. In the figure, the electric kettle includes a kettle body 10, a cover body 20 and a handle 40. The handle 40 is assembled on the kettle body 10, and the cover body 20 can be rotatably covered on the kettle body 10. The electric kettle's tipping-proof and leak-proof automatic control structure of the present invention is configured in the kettle cover and the handle 40.

[0035] The kettle body 10 of the present invention includes an outer shell 11 and an inner liner 12. A gap (not marked) is formed between the outer shell 11 and the inner liner 12, and an electrical connector and a heating assembly (not marked) are arranged in the corresponding gap at the bottom of the outer shell 11. The kettle body 10 of the present invention is also equipped with a kettle seat 30, and a step surface 31 is provided on the kettle seat 30 to facilitate positioning and adaptation with the kettle body 10.

[0036] See also Figure 2 and Figure 4 As shown, the electric kettle dumping anti-leakage automatic control structure of the present invention includes a leakage-proof valve assembly 23 arranged in the cover body 20 and a regulating member 42 arranged in the handle 40.

[0037] like Figure 3 As shown, the cover body 20 of the present invention is molded, and the cover body 20 includes a cover plate 21 and a cover seat 22. A discharge port 221 is provided on the cover plate 21, and the cover plate 21 is adapted to the cover seat 22. A seat plate 211 is formed on the cover plate 21, and a limiting groove 212 and a reinforcing rib (not marked) are provided on the seat plate 211. The limiting groove 212 can be formed by surrounding the reinforcing rib (not marked) or can be molded. The top of the limiting groove 212 can be designed to be an open structure, that is, the top of the limiting groove 212 is open. Of course, the limiting groove 212 can also be designed to be a structure with an air outlet 214 at the top, such as a cover plate is provided on the top of the limiting groove 212, and the cover plate is provided with an air outlet 214 for guiding the steam in the limiting groove 212.

[0038] The bottom of the limiting groove 212 of the present invention is provided with a discharge port 213 for draining the steam in the kettle body 10. The leak-proof valve assembly 23 is arranged in the limiting groove 212, and the regulating component 42 is arranged in the handle 40 and interacts with the leak-proof valve assembly 23.

[0039] Please continue reading Figure 3 As shown, the anti-leakage valve assembly 23 of the present invention includes a driven slider 231, a spring 233 and a sealing valve 232. One end of the driven slider 231 is pressed against the inner surface of the limiting groove 212 through the spring 233, and the other end of the driven slider 231 interacts with the regulating member 42. Among them, a mounting post 217 is configured in the limiting groove 212, one end of the spring 233 is passed through the mounting post 217 and pressed against the inner surface of the limiting groove 212, and the other end of the spring 233 is passed through one end of the driven slider 231 and is limited by a stepped surface (not marked). The sealing valve 232 is detachably mounted on the driven slider 231, and a reverse slope 2311 is provided at the other end of the driven slider 231. Figure 3 As shown, in this embodiment, the reverse slope 2311 is set at an angle of 45°.

[0040] Please continue reading Figure 2As shown, a molded plate body 41 is provided in the handle 40 of the present invention, and the regulating component 42 of the present invention includes a counterweight cavity 43 formed in the plate body 41. The inner edge surface of the counterweight cavity 43 is a cone with a larger upper portion and a smaller lower portion, and the counterweight cavity 43 is connected to the limiting groove 212 on the side close to the cover body 20, and a rotating shaft 44 is arranged in the counterweight cavity 43. The rotating shaft 44 is equipped with a rotating lever 45 through a torsion spring 46. A positive inclined surface 4511 is provided on one side of the rotating lever 45 to form a wedge-shaped fit with the driven slider 231. The other side of the rotating lever 45 extends toward the inside of the counterweight cavity 43 to form a conical cavity, and a counterweight member 47 is arranged in the conical cavity; one free end of the torsion spring 46 abuts against the limiting column 48, and the other free end of the torsion spring 46 abuts against the rotating lever 45.

[0041] When the kettle body 10 is in a normal upright state, the weight member 47 is at the bottom of the conical cavity because its gravity is greater than the force exerted by the driven slider 231 on the rotating lever 45, that is, the rotating lever 45 exerts a force on the driven slider 231, so that the spring 233 is in a compressed state, and the sealing valve 232 on the driven slider 231 is on the left side of the discharge port 213. In this way, the water vapor in the kettle body 10 can be conducted through the discharge port 213 to the air outlet 214 of the limiting groove 212 and discharged outward, so as to prevent the high-temperature water in the kettle body 10 from overflowing due to boiling.

[0042] When the kettle body 10 is tilted, the counterweight 47 will move toward the top in the counterweight chamber 43, which will reduce the force on the left side of the rotating lever 45, causing the rotating lever 45 to move around the rotating shaft 44, and the driven slider 231 to move toward the side of the counterweight chamber 43, so that the spring 233 will automatically extend, driving the piston valve cover to close at the discharge port 213, so as to achieve its automatic closure, thereby preventing water in the kettle body 10 from overflowing from the discharge port 213 and causing a safety hazard.

[0043] It should be noted that the limit groove 212 of the present invention is connected to the counterweight cavity 43, the plate body 41 is molded and provided with a plurality of reinforcing ribs, the reinforcing ribs enclose a counterweight cavity 43 with openings on two opposite sides and an open structure, and the reinforcing ribs forming the counterweight cavity 43 are all inclined, so that the model can be used to form a conical counterweight cavity 43 of different sizes, and a sealing cover 48 is provided on the counterweight cavity 43, and a sealing ring 49 is provided on the end face of the sealing cover 48. The sealing cover 48 and the reinforcing ribs on the plate body 41 are pressed together through the sealing ring 49 to ensure their sealing performance, thereby ensuring that heat will not be lost when the kettle body 10 is heated.

[0044] like Figure 4As shown, the rotary lever 45 of the present invention includes a sled plate 451 and an L-shaped adjustment plate 452. The sled plate 451 is connected to the adjustment plate 452, and a positive inclined surface 4511 is provided on the free end of the sled plate 451. The adjustment plate 452, the inner edge surface of the counterweight cavity 43 and the sealing cover 48 form a conical cavity that is larger at the top and smaller at the bottom. The counterweight 47 can roll freely and is limited in the conical cavity; a limiting column 48 is provided on the inner edge surface of the sealing cover 48, and one free end of the torsion spring 46 is in contact with the limiting column 48, and the other free end of the torsion spring 46 is in contact with the rotary lever 45, so that when the counterweight 47 moves, the torsion spring 46 can quickly react to control the rotation of the rotary lever 45.

[0045] The sealing cover 48 of the present invention is closed after covering the counterweight chamber 43 to form an opening on one side connected to the limit groove 212, so that the sled 451 of the rotary dial rod 45 extends into the limit groove 212, and the positive inclined surface 4511 and the reverse inclined surface 2311 of the driven slider 231 form a wedge-shaped action surface. Combined with the contraction of the spring 233, the sealing valve 232 can be made to slide left and right relative to the opening, thereby achieving the purpose of preventing water leakage due to tilting. Due to the action of the torsion spring 46 and the counterweight 47, its mechanical automatic opening or closing can be achieved, so that when the kettle body 10 tilts, the counterweight 47 can roll up and down freely, resulting in a change in the left and right force of the rotating torsion spring 46, thereby changing the force on the driven slider 231 and achieving the left and right sliding of the driven slider 231. Moreover, the structure of the torsion spring 46 can be used to achieve automatic recovery of the rotating torsion spring 46 after losing its binding force, thereby ensuring the reaction speed of the driven slider 231.

[0046] The electric kettle of the present invention has a tipping-proof and leak-proof automatic control structure, in which a conical counterweight cavity 43 with a larger upper portion and a smaller lower portion is provided in the handle 40. A counterweight 47 is engaged with one end of a rotating lever 45, and the other end of the rotating lever 45 is wedge-shaped and adapted to the driven slider 231. When the angle of the kettle changes, the counterweight 47 slides up and down in the counterweight cavity 43, thereby causing the rotating lever 45 to rotate around the rotating shaft 44, so that the end of the rotating lever 45 interacts with the driven slider 231 to drive the driven slider 231 to move left and right, thereby realizing automatic closure of the sealing cover 48 on the driven slider 231 and the discharge port 213.

[0047] In this embodiment, a sealing gasket 13 is provided at the bottom of the lid 20 of the present invention, which is pressed against the kettle body 10 , so as to keep the hot water in the kettle body 10 warm.
